IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 167,220, dated August31, 1875; application filed August 2,1875.

To all whom it may concern Be it known that I, ALBERT A. CARTER, ofPhiladelphia, Pennsylvania, have invented a new and useful improvementin screens for excluding dust and insects from buildings, ap-- plicableto windows and doorways and other openings; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to'the accompanying drawing and letters of referencemarked thereon.

The nature of my invention consists in the novel form of the moldings,and of the metallic parts for uniting them, and forming the pivots orjoints and fastenings so that persons of slight mechanical skill canquickly and easily make and fit a door or window opening with ascreen-frame with but a slight expenditure of material.

Figure 1 shows an elevation of the screen; Fig. 2, a section of themolding; Fig. 3, a detached view of the pivot; Fig. 4, a detached viewof the an gle-piece for fastening the frame in position.

The same letters of reference apply to the same parts in the severalfigures.

A is the cross-bar, equal in length to the width of the window opening.B and B are doors, made by mitering together moldings marked 0. (Shownin Fig. 2 in cross'section.)

It will be seen, on inspection, that the molding O is shaped on oneside, 0 so that it forms a segment of a cylinder, and on the other israbbeted, so as to form a right angle, 0 The right angle 0 fits againstthe lower edge of the sash of the window when the moldingis made intothe cross-bar A. When made into the frame B the surface 0 fits againstthe bar A at the top, and the surface (J at the bottom or sill Y of thewindow-frame, and the cylindrical surface 0 fits against the sides ofthe window-frame Z, in the outer sides of the frame B. D are pivots orscrews, formed with collars D on them, and projecting heads D whichanswer the purpose of journals or hinge-pivots, as well as means ofholding them and turning them to screw them into the frame. These pivotsare inserted concentric with the axis of the cylindrical part (J of theouter sides of the frame (3, and turn in holes bored in the sill Y andbar A. E and E are angle-pieces for screwing the cross-bar A to thesides Z of the window. Buttons F and F serve to hold the frames or doorsB when closed. The frames B are covered with metallic or other netting.

The advantages of this invention are, that with one single form ofmolding I am enabled to fit any rectangular opening with frames which donot interfere with the sliding motion of the sash, and are very stronglymade with a minimum of material and workmanship.

What I claim as my invention is The combination of the frames B, formedof the molding described and shown, with the collar screw-pivots D, barA, and angle-piece E, constructed as set forth and described.
